In 2009 Juniper Research predicted that the total market for cloud-based mobile applications will rise from a little more than $400 million in 2009 to nearly $9.5 billion by 2014, at an average annual increase of 88%.

It’s all because the guys that build computer networks find it easier to draw a cloud to represent all the connections that make up the Internet

The “cloud” is a word referring to all the hundreds of Internet connections involved in sending your emails, for example. Put simply, your email goes through a “cloud” of multiple Internet connections.

As the Internet grew, all the connections on the Internet became known as the “cloud”.

Techies realized that they could do more than just provide connections in the cloud, they could actually hook up big computers with super computing power in the cloud and share these big computers with lots of people. With this idea, cloud computing was born.

Think of cloud computing as literally a giant computer that you can access on the Internet. So now in addition to your personal computers, with cloud computing you now have another big computer in the cloud.

The Cloud is a term for describing ways of using the Internet to plug into the collective power of hundreds or thousands of computers and turning your own home computer, laptop or smartphone into a doorway to a massive supercomputer that is at your beck and call 24 hours a day and quite often even for free.

Cloud computing is the ability to employ a number of computers, hardware, software, and servers to serve your computing needs remotely without actually owning or running the software and hardware.

“Your files are actually safer while stored in your Dropbox than on your computer in some cases. We use the same secure methods as banks.

Dropbox takes the security of your files and of our software very seriously. We use the best tools and engineering practices available to build our software, and we have smart people making sure that Dropbox remains secure. Your files are backed-up, stored securely, and password-protected via Secure Sockets Layer (SSL) and AES-256 bit encryption. Dropbox uses Amazon's Simple Storage Service (S3) for storage, which has a robust security policy of its own.”

Supporters also argue that, essentially, most office-based PCs are Internet connected, so in theory they’re no more exposed when using the cloud. And some would argue that by using cloud technology, businesses are passing their data to experts that are also experts in protecting it, instead of an on-site machine that might be out-of-date and potentially at risk of attack.

MANY CLOUD SECURITY FIRMS arespringing up to add extra layers of security for cloud computing companies

“In a few years, no-one will consider how secure cloud computing is because there will be few alternatives.” Nick Marshall, Giacom World Networks

Good idea to not rely only on Cloud for storing your data - have a local version as well - e.g. Gmail and Gdocs (use GooBackup for hard drive storage or on another Cloud service). Dropbox has this double-location safety automatically.
